Mod Unity How do I mod Huniepop CGs/Backgrounds? (Unscrambling/Rescrambling Unity Atlas images)

[jai_investigator]

So just for the hell of it I thought I would try to see if I could make a quick mod to replace some of the CG images in the game Huniepop. I've figured out how to use unity resource extraction tools to find the resource I want, modify them, and even how put them back in.

The problem is that for CGs the images are several images that are scrambled (see example attached). From what I can gather this is because they have been processed through a 2d Texture atlas. So I was wondering if anyone knew how to unscramble these images, so I can modify/replace them, and then re-scramble the modified/replaced image to put them back in the asset pack.

I have found these tools specifically for Huniepop sprites that look like they may do the job

but when I build them I can't figure out exactly how to use them...

Hoping someone here knows how I could do it or can point me in the right direction!

I don't know much of anything about it, but from what I can see is that it isn't just one image, but rather all 4 variants. Good luck soldier.
